Improved reliability of uroflowmetry investigations: results of a portable home-based uroflowmetry study.

OBJECTIVES To compare the results obtained using a portable home-based uroflowmeter with the results of traditional flowmetry performed in the out-patient department (OPD). PATIENTS AND METHODS Sixty-seven patients (mean age 61 years, range 38-79) with lower urinary tract symptoms and/or benign prostatic enlargement used a home-based uroflowmeter comprising a datalogger and specially designed fluid sensors incorporated into disposable beakers. The results of these measurements were compared with those from uroflowmetry in the OPD and with other clinical variables. RESULTS There was a good correlation between the uroflow results obtained when voiding at home and at the OPD. The highest measured maximum flow and voided volume were obtained with the home-based uroflowmeter system. However, the mean of all consecutive home-based maximum flow and voided volume measurements were lower than those obtained by single-void uroflowmetry in the OPD. CONCLUSIONS Home-based uroflowmetry provides reliable voiding results which are comparable with those obtained in the OPD.
